Either I or II follows
Neither I nor II follows
Both I and II follow
Answer: Option
Explanation:
The Commissioner only cites examples of cities X and Y and undertakes to beautify city Z. This does not imply that he has worked in cities X and Y. So, I do not follow. Also, nothing about people's response to the state of the city can be deduced from the statement. Thus, II also does not follow.
